application l may covwern: it lino .n l, Gnnann P, YOUNG, a, citizen of the United States, residing at Dayton, in. the county of ltdontgomery and State of Uhio, have invented certain new anduseful improvements in Decarbonizing Compounds, of which the following is a specification The invention relates to a compound for removins carbon from an internal combustion engine, the broad object in view being to provide a compound which will act as a solvent for the gummy binder which holds the particles of carbon together and upon the various surfaces of the engine, which compound also serves to intensify the heat in the combustion chamber of the engine and thereby causes the particles of carbon to be quickly brought to a condition of incandescence, whereupon the greater portion of the carbon particles are consumed while the unconsumed particles'are carried out by the out-rushing exhaust gases.

The compound consists of a mixture of carbon disulfid, about ethyl alcohol, about 17.5% benzol, about 32.5% and ordinary commercial gasoline, about 5%.

The mixture operates to dissolve the gummy binder which holds the particles of carbon together in the deposit on the in-.

ternal surfaces of the combustion engine, including the spark plugs. To remove the carbon deposit, a small quantity, say from two to three ounces of the compound is poured through the spark plug holes of the cylinders and the spark plugs are then screwed into place so as to prevent too rapid evaporation of the compound. The compound is allowed to remain in the cylinders for at least an hour and preferably for several hours or all night and although the compound may be introduced into the cylinders while the engine is hot or cold, it is preferred to use the decarbonizer while the engine is heated, as the heat in the combustion chambers will gasify the compound and cause it to search out all carbon deposits and dissolve the gummy binders, thereby freeing the particles from each other. Then when the engine is started, the particles of carbon are quickly brought to an incandescent state where they are consumed by the explosive mixture. The mixture referred to is productive of a very high degree of heat and this greatly facilitates combustion and causes the particles to be consumed. Any carbon not consumed in this way is carried out through the exhaust ports of the engine. Thus the engine is cleaned without injury to any of the parts or surfaces upon which the carbon has accumulated and without adhering to the valve faces or seats and thereby reducing compression: The compound may also be used to clean spark plugs and other surfaces, such parts being removed from the engine and submerged in the solu tion, The compound acts in the same manner upon such surfaces, dissolving the binder and enabling the carbon to be easily scraped, brushed, or otherwise removed from the spark plugs or other parts.

I claim:

A decarbonizing compound consisting of carbon disulfid, about 45% ethyl alcohol, about 17.5%; benzol, about 32.5%; and gasoline, about 5%;

In testimony whereof I affix my signature.
